I loved Krypton too. The writing and acting were strong, especially for the villains and the Zod family. Seg was good too, and only got better. Doomsday backstory was really good I think and unexpected. So disapponted this show ended so soon.
The only thing I didn't like was Lyta being Seg's true love. It felt so wrong. Nyssa should have been the one. Lobo was also annoying to me. Not sure it was the actor or the writing/direction.
